Summary on Grant Application Form |

The research is concerned with structural identifiability of parametric models, namely whether the unknown parameter of a postulated tool could be identified from a specified input-output experiment if the perfect data were available. For linear systems, the topic is largely understood, but only a few techniques applicable to nonlinear systems are currently available. Considerable simplification in nonlinear system identifiability analysis can be made by splitting the rpoblem into linear and nonlinear parts, but the underlying assumption of a linear isomorphism needs to be investigated.Identifibility analysis has been made much easier by the use of computer packages employing symbolic manipulation and coputer algebra, and part of the research will be to apply the lastest versions of such packages to the nonlinear system identifiability problem. As part of this work, a new computer program, developed by a team from the Unis of Cagliari and Padova, will be investigated. For unidentifiable models, it is possbile to re-parameterise the model, and the link between the reparameterisation and Greobner bases will be established. The most appropriate reparameterisation for a particular system will be examined.The work will be applied to modesl from a wide range of applications, in particular parametric models of electronic nose experiments.
